CHANGE

April 25, 2012

FN7640.1

1. Expanded the maximum temperature from 85°C to 105°C for the electrical characteristics and Ordering

Information.

2. Added application design guide for selection of inductor and capacitor and loop compensation.

3. Added typical electrical specification of EN pull-up current, synchronization.

4. Added boost-buck efficiency curve and AUVVCC switchover description.

5. Under "Output Voltage" description, corrected "(1/Fs tMINOFF)" To " (1 - Fs * tMIN(OFF))".

6. Under "Boost Converter Operation", corrected "(VIN*IIN = VOUT*IOUT*Efficiency)" to "(VIN*IIN =

VOUT*IOUT/Efficiency)".

7. Added recommendation of the maximum programmable OC threshold to be 4.18A(TYP) with 71.5k RLIM.

8. Corrected sentence in first paragraph on page 1 from: “ The ISL85402 supports a wide input range of 3V to

40V in buck mode.“ to “ The ISL85402 supports a wide input range of 3V to 36V in buck mode.“

9. Removed following sentence from last paragraph of “Power Stage Transfer Functions” on page 19: “Deleted

following sentence from last paragraph of “Power Stage Transfer Functions” on page 19: “A capacitor (<1nF)

at the FB pin to ground also helps proper PFM mode operation".
